	Re: Future of McKoi? by Alex Molochnikov :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Alexander, Thank you for the quick response. However, the reason I asked the question is different from what your answer implied. I am not searching for an RDBMS. Our product (SCRIBE report generator) currently supports McKoi, among other databases. So, I just wanted to gauge whether there is any point to continue keeping McKoi on the list.

Learn more about Nabble's security policy. I am interested in the Mckoi database because I think it has been the best one I've seen among all the pure Java databases I've evaluated. I have tried pointbase, h2, hsqldb and cloudscape/derby, in the context of a fairly large CRM app I have been involved with. Each had its own set of issues. Pointbase wasn't as fast, nor was cloudscape or h2 (at the time I tested them -- a few years ago). hsqldb was actually quite a bit faster, but I seem to recall that it wasn't supporting transactions properly. I even tried sqlite, but there were some issues with blob support in its JDBC driver. By contrast, I've had Mckoi deployed in production for quite a while now, and never had a hiccup -- no data corruptions, no management headaches, nothing. It just works. So it be a real pity to see this project die. Regards. M. A. Sridhar `m_a_sridhar at yahoo dot com` ----- Original Message ---- From: Alexander Finger <alexander.finger@...> To: mckoidb@...

Learn more about Nabble's security policy. That is interesting. I originally chose McKoi for my project and used it for the first few months of development. It started getting corrupted very early in the testing phase and did this several times. I couldn't get much help and no recovery schemes seemed to work. I switched to Hsqldb over a year ago as it had all the features of McKoi except for the Java Object data type. Actually, it turned out to be considerably faster too. The database has been in production for almost 6 months now. A few weeks ago, I updated to Java 1.6 and started getting corrupted index or internal pointers or something. Fortunately, Hsqldb does have pretty good recovery tools so I lost almost no data. I looked at Derby, especially since Sun has adopted it as JavaDB. It is reported to be considerably slower then Hsqldb and it does not support the Boolean data type which is scattered throughout my application. The conversion would be too much.

	Re: Future of McKoi? by Bayless Kirtley :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Some parts of this message have been removed. Learn more about Nabble's security policy. The current version of Hsqldb supports transactions only in isolation mode READ_UNCOMMITTED. I discovered this when trying to correct the problems brought on by updating to Java 1.6. I was trying to eliminate any other problems that might be caused by poor application programming. When queried, JDBC reported READ_COMMITTED mode as I had set it when that was not actually true. As a result, I changed a lot of the application to AUTO-COMMIT wherever it was practical. According to the developers, the next revision will handle all transaction isolation properly although it sounds like with some additional overhead. BTW, Hsqldb is now handled by Sourceforge. That should be a good thing. Bayless ----- Original Message ----- From: m_a_sridhar@... To: mckoidb@... Sent: Monday, January 28, 2008 2:57 PM Subject: Re: Future of McKoi?
